Wide angle image capturing device for use in, e.g., airplane, has unit selecting light beam that is representative of region of interest of image, and movable digital camera capturing selected beam only

摘要

The device has a reflector (5) for reflecting a light beam (4) corresponding to a wide field. A selecting unit selects a light beam (4') from the beam (4). The beam (4') corresponds to a field reduced from the wide field, and is representative of any region of interest (52) of a wide field image (42). A movable digital camera (20) is arranged downstream of the reflector. The camera captures only the beam (4'). Independent claims are also included for the following: (a) a method of capturing an image acquired by a large field optical system; and (b) an image capturing system comprising a capturing device.
